Why it works: Shallot and onion match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 2,431 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
A Fish Currie
Ingredients
Directions
Prepare
Cut the soaked fish into pieces.
Combine the fish with enough water to cover it in a pot and mix in the curry powder.
Cook and serve
Melt the butter in a skillet and fry the minced shallot and onions with pepper and salt until browned.
Add the browned mixture to the fish and stew everything together until the fish is tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish and turns tender as it stews.
- Butter
- Adds fat and richness, helping the onions brown and carry flavour.
- Onions
- Browned to build sweetness and savoury depth in the curry base.
- Curry powder
- Provides the spice blend that gives the dish its characteristic flavour.
The step that matters
Browning the shallot and onions. Frying until properly browned develops sweet, deep flavours through caramelisation. Pale, under-browned onions leave the curry tasting flat and raw.
Swap the shallot
How well each one fits the dish's main ingredients (fish, butter, onion, pepper):
- Potatofits better
- Capsicumfits better
- Chivefits better
- Shallotthe original
Fit is the average pairing score against fish, butter, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
